SPnorFIcArIoN. To all whom it may concern: Be it known that I, ALLEN O. BURNER, of Green Bank, in the county of Pocahontas and State of West Virginia, have invented a new and useful Improvement in Mechanical Move 'ments; and I do hereby declare the following I to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, in which--- Figure l is a perspective view of my invention applied to a carriage. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation of the same. Fig. 4 is a sectional plan of steering devices. Fig. 5 is a sectional view of the That others may fully understand my inventon, I will particularly describe it.

I propose to employ a series of heavy cams, alternately acting against levers or rods'connected to a corresponding series of cranks upon the main axle. Said cams I propose shall be of weight sufficient to effect the required revolution of the main axle, so that friction at the axle upon which said cams revolve will be mainly neutralized, as the weight of said cams will rest upon the levers orconnecting-rods, and be thereby imposed upon the main axle, insltead of restinginthe bearings of the camax e.

I do not propose to confine myself to locomotive-carriages in applying my invention, as it will appear evident that it may be applied as a motor for shop purposes with equal facility.

A is the main axle, which is constructed with a series of cranks, B, preferably four or more in number. These cranks may be located at the ends of the main axle A when the machine is not intended for locomotive purposes. The cranks B B are set so as to receive power successivelyat the same pointin their revolution, as shown in Fig. 2. The connectingrods 0 G transmit power to the cranks B B. These rods are jointed at their upper ends to the levers D D, though they may be jointed to guides moving in vertical ways when the machine is in tended to be stationary. The levers D are shown as jointed to studs E at the rear end of the platform F, upon which the mechanism rests. The driving-cams G G are mounted upon an axle, H, which is supported, in any suitable manner, above the levers. D. In the drawing said cams are shown as being sup ported by a stationary frame, I 5 but, as the weight of said cams should be sufficient to drive the machine, the frame I may be made inclined and pivoted at its foot to the rear end of the platform, at or near the point where the levers D D are pivoted, and the entire weight of cams and frame will then rest upon the levers D, and the weight of said frame will then be utilized. This arrangement is shown by dotted lines in Fig. 2. Friction-rollers J J are located upon the levers D to receive the action of the cams G G and decrease frictional resistance. The cams G G are so formed that each actuates its crank upon the main axle during a certain part of its revolution, and the several cams are so adjusted to each other that one comes into action a little in advance of its predecessors ceasing to act, as is clearly shown in Fig. 2.

pulleys may be employed, as shown in Fig.

2, instead of rods K and cranks or eccentrics. The cams G may be rotated by power applied to the treadles L, by cranks, or by any other means.

When used for locomotive purposes means for steering are required. I attach the platform F to a stationary ring, M, which supports the bearings of the main axle. The ring M has an annular groove in its edge, into which i is fitted a ring, N, and to this latter ring the hounds or braces b for the perch O are attached, as shown clearly in Fig. 4. Upon one side of .the ring N I make a rack, and a pinion, P, meshing with said rack, enables the conductor to vary the angular position of the main axle with reference to the perch at will. For this purpose the pinion P is provided with a crank, Q, or other means of operating it at pleasure. It is a friction-wheel, placed on the perch O to support the rear end of the platform F and enable it to pass from side to, side with ease in the operation of changing line of progression. In order to enable the wheels to pass over obstruction in the road with the least possible disturbance of the machinery the rear axle S is pivoted to the rear end of the perch O, and is supported in its correct position by the braces T '1, and said braces are rigidly secured to a collar, U, loosely placed on the perch O.

Clutches V may be placed upon the axle A to render the front Wheels fast or loose, as may be required.

Having described my invention, what I claim as new 1s- 1. The combination of the heavy cams G G with the connecting-rods C C and cranks B B upon the main axle A, substantially as de scribed.

2. In combination with the cams G, connecting-rods O, and cranks B, the eccentric or crank-rods K K, substantially as described.

3. The pivoted levers D D, in combination with cams Gr, connecting-rods G, and cranks B upon'the axle A, substantially as set forth.

4. In combination with the axle A and ring M, the rack-rin g N and steering-pinion 1?, substantially as set forth.
